https://www.csm.org.pt/ficheiros/arquivo/juizes/quadros/quad...On page 15 there's a list of judges from the "TJ Comarca Setúbal" - "Instância Central Setubal" - "Secção Criminal"
Juiz 1 Paula Alexandra Robalo de Sá Couto
Juiz 2 Maria de Fátima Cardoso Bernardes
Juiz 3 António José Martins Berenguer Cabral
Juiz 4 Belmira do Rosário Faísco Vieira Fialho Raposo Felgueiras

So, I have to agree with Clauwolf....it's just a numbering system for the judges that belong in each section of a specific court.
